I have been wanting to get a Springfield Armory Mil-Spec but have been wondering about the titanium firing pin that they use to meet the California requirements. I believe they use a firing pin from a 38 super in the 45acp made from titanium to help meet the drop test for the state of California.
Can this firing pin be replaced with a "normal" firing pin?
Can you replace it with a firing pin from a 45acp?
I am imagining that the firing pin hole in the breech face is fit for the 38 super firing pin and one from a 45 probably wouldn't fit through the hole.
I just do not like this change from the norm just to satisfy the state of California.
Anyone know about this?

SA uses a 9mm/38 super Ti firing pin. It can be replaced with a 9mm/38 super steel fp.

The ILS MSH can be replaced with another MSH. Fitting (i.e. filing MSH) may be needed, but likely not if it's a reputable part. You'll need the MSH guts as well.

Mine has one, and it has nothing to do with California, it's in every Loaded. Flawless. No need to replace. Enjoy.

Are you talking about the locking system or the firing pin?
The titanium firing pin is definately about California. The locking system is definately about some unnecessary added crap that a 1911 doesn't need.
I didn't care for the series 80 system that Colt came out with, even though I have a couple of them.
I don't like the idea of adding another unnecessary safety or a mutant firing pin that is unique to this one gun.
Other than that it is a fine weapon with a lot of potential.

They may use it in west cost bound MilSpecs to satisfy some gay Cali requirement, but they're included in all Loaded models, nothing to do with state requirements. It's an upgrade, not something to rush to undo.

don't replace it. all springer 1911's have a titanium FP, not just the Cali market ones. it's part of their drop safety (coupled with a heavy FP spring). works fine, and it's a safety. leave it alone, my friend

One more thing I forgot about.
Can the ILS be eliminated simply by replacing the mainspring housing and related components?

Yup, it sure can. It's a very easy swap out too, total cost will be around $50 to $60 for the MSH and assorted parts. I've done it several times now.

Some say replace the hammer strut while you're at it because supposedly the stock hammer strut is shorter to work in conjunction with the ILS. In my experience though that's been bogus info about the hammer struts, the stock ones work fine with the replacement MSH and parts. I went ahead and replaced my hammer strut on one of my Mil Specs anyway for something more durable just because I wanted to.

I had no idea that 1911's would fire when dropped (unless their pin was titanium). Had I known that, I'd never have purchased one.

The titanium pin is Springfield's way to meet this...others use other systems...I imagine all current manufacturers have this covered in some way...Swarts, Series 80...I wouldn't let this be a concern...

It's not that I mind the titanium firing pin. That's not a big deal.
What I don't like is that they redesigned the gun to take a firing pin from a 38 super/9mm gun and put it on the 45acp. It was done to satisfy the drop test in California without adding a series 80 type of trigger block.
The lighter (titanium) and smaller firing pin does not have the mass to actually hit the primer hard enough to fire a round from a hammer down position when the hammer is hit such as in a dropped gun.
Unneeded as far as I'm concerned because the gun should be carried in the hammer back, thumb safety on (condition one) condition and it wouldn't be an issue.
The gun is now a 1911 only with a smaller hole in the breech face for the smaller firing pin. Making it a 1911, only different.
All to satisfy a state that prohibits most people from carrying the gun in the first place.
I know it makes no difference to how the gun shoots, and most people would not care or even be aware of this.
I am a 1911 purist. I think the 1911's are fine the way they were and I didn't care for the changes made to the series 80 guns either.
If you don't want to carry a 1911 in condition one then get another gun. Leave "our" gun alone because me and a bunch of other people like them the way they are, or should be.
I'm holding off and looking at other guns.
